People in Microsoft (particularly middle managers) were also alerting other employees that something was going on through LinkedIn alerts. All of a sudden, a lot of Microsoft employees started updating their LinkedIn profiles and photos.

Although most of the Microsoft employees being let go should have found out today, Nadella has also put everyone on notice for the next six months. There's still 5,000 cuts left to make, and that's stressing people out, the source says.

"The next six months will be a drain on morale," our source says. "Cut now! Get the surgery over with and move on."

Then again, Microsoft also has about 3,200 job openings, according to Glassdoor.com. So perhaps some portion of those people will transfer to a new team in the next six months, instead of leaving the company altogether.
